Abstract

Introduction: Periodontal ligament plays an essential role in preventing relapse after orthodontic treatment. Hyperbaric Oxygen Therapy (HBOT) and propolis gel can increase the amount of fibroblast in the tension area during orthodontic treatment, thus affecting the periodontal ligament. This research was aimed to analyse the difference of the width of the periodontal ligament and amount of fibroblast in the tension area with the administration of propolis gel and HBOT in an attempt to prevent orthodontic relapse. Methods: Forty-two male guinea pigs were randomly divided into 7 groups of treatments― the untreated group (I – negative group), group with rubber separator (II – positive group), 3% propolis gel treatment group (III), 5% propolis gel treatment group (IV), the HBOT treatment group (V), combination of 3% propolis gel and HBOT treatment group, and combination of 5% propolis gel and HBOT treatment group. The upper left central incisor was extracted distally using a 14-days separator rubber in the positive group and the treatment group; then the separator rubber was removed for 2 days to conduct the relapse process. The data were analysed by LSD statistical test. Results: The result of the combination of HBOT and propolis gel treatment showed significant differences among all groups (p<0.05) in the width of the periodontal ligament (1.03), and the number of fibroblasts was 95.67 in the tension site. Conclusions: The combination of HBOT and propolis gel affect the width of periodontal ligament and the number of fibroblasts in the area of the orthodontic relapse.

Abstract

Background: Bone augmentation requires biomaterials that can trigger bone regeneration, especially when treating alveolar bone defects. Biphasic calcium phosphate (BCP) can induce cell proliferation and differentiation. Anadara granosa shell can be synthesized into BCP and made into a scaffold with the addition of gelatin. Purpose: To determine the optimal BCP ratio from A. granosa shell synthesis and to establish the material characteristics. Methods: Anadara granosa shells were synthesized using the hydrothermal method at 200°C for 12 and 18 hours, followed by particle size analysis. Next, the resulting powder was made into scaffolds by adding gelatin through the freeze-drying method, and a series of observations were performed regarding its morphology, pore size, porosity, compressive strength (CS), and cell viability. The data were analyzed using an independent t-test, with p < 0.05. Results: Synthesis of A. granosa shells for 12 hours produced a BCP ratio of 69:20 with 11% calcite content and a particle size of 3,343.00 ± 445.25 nm, whereas synthesis for 18 hours produced a ratio of 22:78 with a particle size of 919.96 ± 375.77 nm. In scaffold manufacture, the BCP18 pore size (26.56–145.45) was smaller than that of BCP12 (19.72–309.09), the porosity level was lower (61.49% vs. 81.98%, respectively), and the CS was higher (4.66 ± 1.12 vs. 2.89 ± 0.799, respectively). Nevertheless, both had relatively good cell viability (≥50%). Conclusion: Biphasic calcium phosphate obtained from A. granosa shell synthesis exhibits varying ratios; nevertheless, both variants possess favorable attributes for consideration as potential bone substitute materials, as they meet the necessary biocompatibility requirements.
